3, conveyor belt and causes damage in the form of
(A) the conveyor belt causes longitudinal tear
1. Vibration impact caused by fasteners loose and fall off, resulting in coal drop pipe linings, guided material board crashed.
2. Material within the mixed foreign body, foreign body hard, angular, coal drop pipe plug Jisi.
3. Roller defects, scratches caused by roller frame.
4. Polyester Conveyor Belt rack to hang after a serious deviation.
5. Involved in roller cleaning device (cleaning device return), bolt loose, there are bouncing in anticipation.
(B) the reasons for cracking conveyor belt
1. Size due to space constraints, the curved conveyor belt more times.
2. Joint curing time for various reasons been more than two curing.
(C) the reasons for curing joint tear
1. Bend pulley diameter is small, the conveyor system to bear great bending stress.
2. Sulfide poor quality joints, especially in curing more than twice, the joint strength decreased, or when the canvas at the bonding layer has been cut, or polished leak, here reduced intensity.
3. For the reversible conveyor, due to overlap from top to bottom can only be in one direction, easily on a belt cleaning devices, devices such as sharp points discharge scratch.
4. Conveyor work cycle is short, frequent starting, instantaneous power of great tension.
(D) the reasons for covering the damage of rubber cover
1. I. Trough the gap between the liner and the tape inappropriate, causing abnormal wear and tear, or the gap at embedded foreign body, causing abnormal wear and tear, or scratch.
2. I. Trough Department Stores velocity is inconsistent with the conveyor speed, drop large plastic surface to accelerate wear and tear.
3. Roller is damaged, resulting in abnormal wear and tear or scratch tape.
4. Illegal operations, maintenance burns when welding slag.
5. Sweeper scratch.
6. Skid tape, adhesive tape can also cause abnormal wear and tear.
